Nothing found in peculiar wells - what's the point in being inflamed? (7)
I believe the answer is:
Here is my best explanation:
'being inflamed?' is the definition.
'nothing found in peculiar wells what's the point' is the subsidiary indication.
'nothing' becomes 'o' (looks like zero - 0).
'found in' is an insertion indicator.
'peculiar' indicates anagramming the letters (I've seen this in other clues).
'what's the point' becomes 'n' (N is an example).
'wellsn' is an anagram of 'swllen'.
'o' inserted within 'swllen' is 'swollen'.
'in' is the link.
(Other definitions for swollen that I've seen before include "Sell now (anag)", "Bulging", "Protuberant", "Puffed up", "Inflamed", "All puffed up!", "Tumescent", "Abnormally expanded", "Enlarged" and "Bloated".)
